Anthracite Grey vs Agate Grey: Which uPVC Window Colour Is Right?
Spray Genius Team·February 18, 20267 min read
Two of the most popular grey window colours in the UK compared side-by-side, with guidance on which suits your home.
The quick answer
Anthracite Grey (RAL 7016) is darker, cooler and more dramatic. Agate Grey (RAL 7038) is lighter, softer and reads almost as a warm taupe in sunlight.
When to pick anthracite
Anthracite suits modern, white-rendered homes, dark brick properties, and anywhere you want strong contrast against pale walls.
When to pick agate
Agate is the safer pick for period properties, cottages, and homes with mixed materials. It's understated and tends to age more gracefully visually.
